I've been granted admin access to an internal IIS server on which I need to set up a web site.

Before doing anything technical I wanted to ensure that I could access the server, but when attempting to access a simple page (that does not refer to Sharepoint) at

http://localhost/index.html 

when logged onto the server directly, I am getting

Parser Error

To be quite honest I know zip about Sharepoint, so why am I getting a sharepoint error on a basic "hello world" html page?

Cheers :)

Update: I've since supposedly uninstalled Sharepoint, but am still getting this error. Any ideas welcome!
